We report a 10-year-old boy with unusually dense, bilateral central posterior capsule pigmentation associated with the characteristic clinical features of pigment dispersion syndrome, including Krukenberg’s spindle and dense trabecular pigmentation in both eyes. There was no history of trauma , laser or intraocular surgeries . The presence of posterior or backward bowing of iris suggested a reverse pupillary block mechanism of pigment dispersion syndrome. Nd Yag laser peripheral iridotomy was performed in both eyes to relieve reverse pupillary block. Anterior segment optical coherence tomography (AS-OCT) showed reversal of iris concavity after laser iridotomy.

Pigment Dispersion Syndrome

Introduction: Pigmentary Glaucoma (PG) and Pigment Dispersion Syndrome (PDS) are two different spectrums of a single disease. Since the disease is seen in younger population and is rapidly progressive blinding disease, therefore early diagnosis and treatment will reduce the burden of the disease and improve the quality of life. Aim: To evaluate clinical characteristics of PDS and PG patients in eastern part of Uttar Pradesh. Materials and Methods: This was a two years (1st January 2018 to 31st December 2019) hospital‑based retrospective cross‑sectional study of patients who attended the glaucoma clinic. Diagnosis of PDS was made when they had normal optic disc, normal visual field {with or without increased Intra Ocular Pressure (IOP)} and at least two of the following three signs were found clinically: Krukenberg spindle, homogenous moderate‑to‑heavy (≥Spaeth 2+) Trabecular Meshwork (TM) pigmentation, and any degree of zonular and/or lenticular pigment granule dusting. Patients with PDS were diagnosed with PG, if they had two or more of the following findings: initial IOP >21 mmHg, glaucomatous optic nerve damage or glaucomatous visual field loss. Various parameters such as influence of demographics, IOP, Best‑Corrected Visual Acuity (BCVA), Central Corneal Thickness (CCT), Mean Deviation (MD), Visual Field Index (VFI %), spherical equivalent and clinical finding of anterior segment of study patients were analysed. Mean, standard deviation and percentage were calculated using GraphPad Instat version 3.0. Results: Among 40 patients, nine eyes of the six patients had myopia of ‑0.5D or greater, with mean refractive error of ‑3.55±4.72 spherical equivalent. The average baseline IOP in study patients (PDS+PG), was 30.21±11.42 mmHg. Twenty four (60%) patients, either in one or both eyes had glaucoma, secondary to PDS at the initial diagnosis. Thirty three (82.5%) patients had Krukenberg spindles. Homogeneous TM pigmentation was seen in all patients. Typical spoke‑like radial Iris Transillumination Defects (ITDs) were not observed in any of the patients except in one patient, who had isolated short slit‑like trans‑illumination defects in iris crypts. Conclusion: PDS patients with normal optic disc and visual field and raised IOP, should be started prophylactic treatment and needs to be monitored more closely. Thus, the finding of PDS in Indians should alert the ophthalmologist to look for glaucoma during the initial examination.

Aim. To present a clinical case of treatment of pigment dispersion syndrome by clear lens extraction and implantation of a toric intraocular lens in a patient with myopic astigmatism. Methods. A 33-year-old patient with a diagnosis of moderate myopia, complex mild myopic astigmatism, pigment dispersion syndrome of both eyes. Results. The first stage was laser peripheral iridotomy of both eyes. On follow-up pathological irido-zonular contact and increases intraocular pressure by 2 mm persisted. The second stage included clear lens extraction and implantation of a toric multifocal intraocular lens to both eyes. In 2 months, distance and near visual acuity was 1.0, intraocular pressure was normal, no pathological irido-zonular contact was observed according to the ultrasound biomicroscopy. Conclusion. Implantation of an intraocular lens in patients with myopia and pigment dispersion syndrome is both a method of preventing pigment glaucoma and myopia correction; patients with pigment dispersion syndrome after peripheral iridotomy should monitor the state of the anterior segment of the eye and the effectiveness of the treatment by ultrasound biomicroscopy.

Abstract Purpose: To assess the clinical characteristics of comorbid retinal dystrophies and primary angle closure disease.Design: Retrospective study from January 1992 to June 2020.Methods: This descriptive study included 92 eyes of 46 patients with comorbid retinal dystrophies and primary angle closure disease (PACD) that included eyes with primary angle closure suspect, primary angle closure and primary angle closure glaucoma. Demographic profile, clinical characteristics of PACD and its association with retinal dystrophies are described. Results: The study included 46 patients (92 eyes). Males were majority, 63%. Mean (± standard deviation) age when retinal dystrophy was diagnosed was 29.6 ± 9.4 years and PACD was diagnosed at 32.23±7.92 years. Mean BCVA at presentation was 1.07±0.87 log MAR (95% confidence interval (CI):0.87,1.26). Mean Intraocular pressure at diagnosis of glaucoma was 27±16 mmHg (95% CI:23.5,31.5 mmHg). The most common retinal dystrophy associated with PACD was retinitis pigmentosa (RP) followed by RP with retinoschisis. The hospital-based prevalence of PACD among all patients with RP and retinoschisis was 0.19% and 0.15% respectively. Laser peripheral iridotomy (LPI) was performed in 74 eyes (80.5%). Glaucoma was managed medically in majority of the eyes (58 eyes, 63.04%) and minority required surgical management with trabeculectomy (11, 11.9%). Conclusion: Retinitis pigmentosa is the most common retinal dystrophy associated with PACD. Comorbid PACD in eyes with retinal dystrophies was observed in 2nd to 3rd decade of life. This calls for screening for angle closure in eyes with retinal dystrophies from second decade onwards to identify the comorbid PACD and treat or refer them appropriately.
