Purpose To make a visual field retrospective analysis on a group of patients with primary open angle glaucoma (POAG) and to evaluate whether different refractive errors could have different progression of the 30° central sensitivity. Methods A total of 110 patients with POAG (52 men and 58 women) were included in the study. All the patients were divided into four subgroups based on the refractive error. The visual field of all the included patients was assessed by an Octopus 30° central visual field every 6 months, for a total of 837 visual fields examined. The resulting data were analyzed by PERIDATA for Windows 1.7 TREND function. Mean defect (MD) and loss variance (LV) were considered for the analysis. Results At the first examination, 82% of eyes showed a global decrease of differential light sensitivity (MD >2 dB) and in 67% the distribution of the defect was nonhomogeneous (LV >6 dB). The analysis of variance for subgroups showed a more significant decrease of MD in highly myopic patients. A linear regression analysis highlighted a statistically significant change in time of MD in 36% and of LV in 34% of the eyes studied. Highly myopic patients had the highest (p<0.01) percentage of change of MD and LV (46% and 42%, respectively). Among the four subgroups, there was no difference in progression of MD decrease in time. Conclusions These results showed that after 5 years of glaucoma, the visual field was altered in most of the eyes examined (82%) and that in 67% of cases, its defect was nonhomogeneous and worsened with the increase of myopia. The regression linear analysis of visual field changes in time showed a progressive increase of MD and LV in approximately one third of all the eyes examined.

Background: Palpebral ptosis is defined as abnormal drooping of the upper lid, caused by partial or total reduction in levator muscle function. It may be caused by various abnormalities, both congenital and acquired. The aim of this article is to report the long-term follow-up of results obtained with the levator aponeurosis–Müller’s muscle complex readaptation technique. Methods: In a clinical study, 144 eyelids (102 patients) affected by congenital or acquired blepharoptosis were treated using the levator aponeurosis–Müller’s muscle complex readaptation technique. Degree of ptosis and levator function were measured preoperatively and postoperatively. All patients were followed up for 1 year, 54 of them for 3 years, 22 for 5 years, and 12 for 10 years. Results: Complete correction or mild residual ptosis was achieved in over 83 percent. All ptosis with preoperative levator function greater than 8 mm was completely corrected, whereas eyelids with poor or absent levator function showed a variable degree of postoperative correction and a statistically significant difference. Ptosis correction between eyelids with levator function greater than 8 mm or less than 8 mm was analyzed statistically using the McNemar test for paired data. Conclusions: This surgical technique is effective in both acquired and congenital ptosis. In particular, the authors obtained better results in those with fair to good (>8 mm) levator function than in those with poor or absent (≤8 mm) levator function.

Retinal involvement in pigment dispersion syndrome

Gianluca Scuderi; A. Papale; Carlo Nucci; Luciano Cerulli

Retinal involvement has been documented in a number of patients with pigment dispersion syndrome, which also appears to be associated with a higher than normal risk of retinal detachment. We studied 24 patients with this syndrome to determine the prevalence of lattice degeneration and other retinal disorders associated with a predisposition to detachment. Lattice degeneration was found in 8 of 24 patients examined, with a prevalence that is significantly higher than that reported for normal subjects. Four eyes presented areas of retinoschisis and only one displayed a rhegmatogenous detachment. A father and son (both myopes) were found to have similar lattice lesions in the same retinal quadrants. These findings suggest that pigment dispersion syndrome may be associated with developmental anomalies that are not restricted to the anterior chamber but involve other portions of the bulb as well.

Transplantation of autologous cultivated conjunctival epithelium for the restoration of defects in the ocular surface.

Nicolò Scuderi; Carmine Alfano; Guido Paolini; Cinzia Marchese; Gianluca Scuderi

Ocular surface disorders are often characterised by partial or complete loss of corneo-conjunctival epithelium, which causes dramatic functional and cosmetic problems. Depletion of stem cells and the scarcity of donor tissue available make large or bilateral defects challenging to reconstruct, and usually require the transplantation of heterotopic or allogeneic grafts. We investigated the feasibility of restoring severely damaged ocular surfaces with autologous cultivated conjunctival epithelium. Conjunctival cells were harvested from the healthy eyelid bed of four patients with oculopalpebral diseases. An epithelial sheet reproducing the original conjunctival epithelium was generated by serial cell culture. This was transplanted for the first time ever to our knowledge on to the ocular surface of the same patients. Take was excellent and the cultivated epithelium was stable, resulting in great improvement of patients symptoms and cosmesis. Transplantation of cultivated conjunctival cells opens new perspectives in the treatment of severe ocular surface disorders.

OBJECTIVE To evaluate the correlation between tear osmolarity and blood levels of 17-β estradiol, estrone, and testosterone in postmenopausal women with dry eye syndrome, and to assess the efficacy and safety of oral supplementation with phytoestrogens, lipoic acid, and eicosapentaenoic acid in this population. DESIGN Cross-sectional study including 66 postmenopausal women with dry eye syndrome. METHODS Sixty-six postmenopausal women with dry eye syndrome were enrolled in a randomized, double-blind, placebo-controlled, crossover study. Patients were divided into 2 groups (groups A and B) and treated, respectively, with phytoestrogen (Bioos, Montegiorgio, Italy) tablets or placebo tablets for 30 days. The 2 treatment periods were separated by a 30-day washout. Patients were examined on days 0 and 30 of each period. Assessments included blood levels of sex hormones, the Schirmer test for tear production, and measurement of tear osmolarity and tear film break-up time. RESULTS At baseline, all patients had low sex hormone levels, which were correlated with high tear film osmolarity values (r = -0.59,-0.61,-0.58, respectively). After 30 days of therapy, the group treated with Lacrisek® (Bioos) had significantly decreased tear osmolarity (P<0.005) and significantly increased tear production evaluated with the Schirmer test and tear film break-up time values (P<0.001) compared with the placebo-treated group. CONCLUSIONS Our study confirms that steroid hormones play an important role in ocular surface equilibrium and functions. Consequently, reduced blood levels of these hormones can produce changes at the ocular surface. Phytoestrogen supplementation can significantly improve the signs and symptoms of dry eye syndrome in postmenopausal women.

Standard automated perimetry and algorithms for monitoring glaucoma progression

Gianluca Scuderi; Massimo Cesareo; A. Perdicchi; Santi Maria Recupero

Despite increasingly sophisticated techniques for the computerized analysis of the optic nerve and retinal nerve fiber layer, standard automated perimetry (SAP) is still the primary test for assessing functional damage in glaucoma. Most of the diseases affecting the visual field can be studied analyzing the central visual field with a fixed grid of points set at 6 degrees or at a variable density within central 30 degrees, using a III white target stimulus (program 30/2 or 24/2 Humphrey, G1/G2 or 30/2 Octopus). Although there is lack of a true gold standard for glaucoma, SAP results were the primary endpoint in most of the clinical trials in glaucoma. New thresholding strategies allowed a considerable reduction of examination time without substantial loss of accuracy. Moreover, recent findings on structure-function correlation in glaucoma validate the clinical role of this well-known and widespread method of examination.

Pseudoexfoliation Syndrome and Pseudoexfoliation Glaucoma: A Review of the Literature with Updates on Surgical Management

Pasquale Plateroti; Andrea Maria Plateroti; Solmaz Abdolrahimzadeh; Gianluca Scuderi

Pseudoexfoliation syndrome (PES) is a systemic disorder caused by progressive accumulation of extracellular material over various tissues. PES usually determines increased intraocular pressure, changes in the anatomical aspects of the optic nerve, and visual field alterations leading to the diagnosis of pseudoexfoliation glaucoma (PEG). Use of topical medical treatment usually leads to poor results in terms of long-term follow-up but many surgical techniques, such as Argon Laser or Selective Laser Trabeculoplasty, have been proposed for the management of PEG affected patients. The present paper is a review on the pseudoexfoliation syndrome and pseudoexfoliation glaucoma with an update on surgical management.

Laser therapies for glaucoma: new frontiers

Gianluca Scuderi; N. Pasquale

Glaucoma is a long-term ocular neuropathy defined by optic disc or retinal nerve fiber structural abnormalities and visual-field defects. Treatment for glaucoma consists of reducing intraocular pressure (IOP) to an acceptable target range to prevent further optic-nerve damage. Currently available treatments include topical drug (single then multidrug combinations) followed, for those patients on maximal tolerated medical therapy who still need additional IOP reduction, by laser treatments. These included laser iridotomy, laser trabeculoplasty, laser iridoplasty, laser cyclophotocoagulation. Although the various types of laser enjoyed great success as glaucoma therapy for many years, recently the excimer laser trabeculotomy is a promising IOP-lowering technique.

Pediatric Glaucoma: A Literature's Review and Analysis of Surgical Results.

Gianluca Scuderi; Daniela Iacovello; Federica Pranno; Pasquale Plateroti; Luca Scuderi

The purpose of this paper is to review the surgical options available for the management of pediatric glaucoma, to evaluate their advantages and disadvantages together with their long-term efficacy, all with the intent to give guidelines to physicians on which elements are to be considered when taking a surgical decision. Currently there is a range of surgical procedures that are being used for the management of pediatric glaucoma. Within these, some are completely new approaches, while others are improvements of the more traditional procedures. Throughout this vast range of surgical options, angle surgery remains the first choice in mild cases and both goniotomy and trabeculotomy have good success rates. Trabeculectomy with or without mitomycin C (MMC) is preferred in refractory cases, in aphakic eyes, and in older children. GDIs have a good success rate in aphakic eyes. Nonpenetrating deep sclerectomy is still rarely used; nevertheless the results of ongoing studies are encouraging. The different clinical situations should always be weighed against the risks associated with the procedures for the individual patients. Glaucomatous progression can occur many years after its stabilization and at any time during the follow-up period; for this reason life-long assessment is necessary.

Lateral Canthoplasty by the Micro-Mitek Anchor System: 10-Year Review of 96 Patients

Carmine Alfano; Stefano Chiummariello; Cristiano Monarca; Nicolò Scuderi; Gianluca Scuderi

PURPOSE Lateral canthoplasty is useful to correct lower eyelid malposition, restore eyelid function, and protect the ocular surface. An effective method for fixation of soft tissue in the face, such as the lateral canthus, using the Micro-Mitek Anchor System is presented. PATIENTS AND METHODS We report our experience in 96 patients who underwent lateral canthoplasty by Micro-Mitek Anchor. One hundred twenty-four lateral canthoplasties were performed, including, senile ectropion, tumors, trauma, cicatricial retraction, and lower eyelid malposition after blepharoplasty. RESULTS The insertion of a bone anchor requires a limited dissection, and the insertion area can be determined accurately. Using the bone anchor to fixate the lateral canthus to the facial skeleton is an effective way to prevent drooping of the canthus due to gravitational forces. CONCLUSIONS Lateral canthoplasty using the Mitek Anchor System has the advantage of being an easy technique with accurate placement of the anchor, reducing operating time.
