Abstract
PURPOSE To report visual acuity (VA) outcomes, intraoperative and postoperative complications of isolated cataract surgery in eyes with retinitis pigmentosa (RP), compared with non-RP-affected eyes. DESIGN Retrospective clinical cohort study. METHODS A total of 113,389 eyes underwent cataract surgery between July 2003 and March 2015 at 8 clinical sites in the United Kingdom. Eyes with RP as the only comorbid pathology and eyes without any ocular comorbidities (controls) undergoing cataract surgery were compared. VA at 4 to 12 weeks postoperatively and rates of intraoperative and postoperative complications are reported. RESULTS Seventy-two eyes had RP. The mean age in the RP group was 57 ± 15 compared to 75 ± 10 in controls (P < .001). Females represented 46% of RP cases and 60% of controls (P = .06). Preoperative VA (mean LogMAR = 1.03 vs 0.59, P < .001) and postoperative VA (0.71 vs 0.14, P < .001) were worse in RP group. The mean VA gain was 0.25 ± 0.60 LogMAR in RP vs 0.43 ± 0.48 LogMAR in controls (P < .001). There were no significant differences in the rate of intraoperative pupil expansion use, posterior capsular tears, or zonular dialysis. Postoperative cystoid macular edema developed in 6.9% of RP eyes and 1% of controls (P < .001). The need for IOL repositioning or exchange was not statistically different between the two groups. CONCLUSION Cataract surgery can improve vision in eyes with RP and cataract. Intraoperative complications were similar to control eyes; however, RP eyes experienced more frequent postoperative cystoid macular edema.

Abstract
Inherited retinal diseases (IRD) are a leading cause of blindness in the working age population and in children. The scope of this review is to familiarise clinicians and scientists with the current landscape of molecular genetics, clinical phenotype, retinal imaging and therapeutic prospects/completed trials in IRD. Herein we present in a comprehensive and concise manner: (i) macular dystrophies (Stargardt disease (ABCA4), X-linked retinoschisis (RS1), Best disease (BEST1), PRPH2-associated pattern dystrophy, Sorsby fundus dystrophy (TIMP3), and autosomal dominant drusen (EFEMP1)), (ii) cone and cone-rod dystrophies (GUCA1A, PRPH2, ABCA4, KCNV2 and RPGR), (iii) predominant rod or rod-cone dystrophies (retinitis pigmentosa, enhanced S-Cone syndrome (NR2E3), Bietti crystalline corneoretinal dystrophy (CYP4V2)), (iv) Leber congenital amaurosis/early-onset severe retinal dystrophy (GUCY2D, CEP290, CRB1, RDH12, RPE65, TULP1, AIPL1 and NMNAT1), (v) cone dysfunction syndromes (achromatopsia (CNGA3, CNGB3, PDE6C, PDE6H, GNAT2, ATF6), X-linked cone dysfunction with myopia and dichromacy (Bornholm Eye disease; OPN1LW/OPN1MW array), oligocone trichromacy, and blue-cone monochromatism (OPN1LW/OPN1MW array)). Whilst we use the aforementioned classical phenotypic groupings, a key feature of IRD is that it is characterised by tremendous heterogeneity and variable expressivity, with several of the above genes associated with a range of phenotypes.

Abstract
Background Optical coherence tomography (OCT) is a noninvasive, frequently used imaging technology that enables detailed viewing of retina anatomy. It is used to monitor disease progression in retinitis pigmentosa (RP) eyes, including detecting changes in retinal thickness. Purpose The purpose of the study is to determine the clinical presentation and macular morphology in RP eyes using OCT imaging. Methods A retrospective review of case records and OCT scans in eyes diagnosed with RP in two ophthalmic clinics in Nigeria. Biodata, Snellen best-corrected visual acuity (BCVA), intraocular pressure (IOP), vertical cup-to-disc ratio (VCDR), and presence of maculopathy were determined. Data were analyzed using IBM SPSS version 22.0 (IBM Corp. Armonk, NY, USA). Results Fifty-five eyes of 28 patients (18 males and 10 females), with a mean age of 47.16 ± 15.56 years (22-77 years), were studied. 40-49 years was the most frequent age group, 28.6%. Severe visual impairment occurred in 22% of eyes and myopia in 32%. Twenty-nine percent had undergone cataract surgery or had a significant cataract. The mean IOP was 11 mmHg, and the mean VCDR was 0.46. On OCT examination, macular atrophy was the most common finding in 74.5% of eyes, epiretinal membrane in 16.3%, cystoid macular edema in 7.3%, vitreomacular adhesion in 5.4%, and vitreomacular traction in 1.8%. There was no association between macular morphology, macular thickness, and BCVA (P = 0.155, P = 0.424). Conclusion OCT provides information on macula structure in RP eyes. About 14.5% of eyes had a normal macula, while 85.5% had a maculopathy, confirming that RP eyes have a higher rate of maculopathy than non RP eyes. OCT evaluation of an RP eye should be a standard workup for the early detection of such maculopathy and monitoring for disease progression.
