Abstract Background To report the prevalence of ocular abnormalities and investigate visual acuity in a large cohort of retinitis pigmentosa (RP) patients in Western China.Methods The medical records and ophthalmic examination reports of 2127 eyes of 1065 RP patients at one eye hospital were retrospectively reviewed to determined the prevalence of ocular abnormalities and the relationship between best corrected visual acuity (BCVA) and macular abnormalities.Results Nyctalopia (58.2%) and blurred vision (27.1%) were the leading reasons for RP patients to request an ophthalmic examination. BCVA measurements in the better eyes at first clinical presentation showed that 304 patients (28.5%) were categorised as blind and 220 patients (20.7%) as low vision. The most common ocular abnormalities were macular abnormalities (59.7%) and cataracts (43.1%). The macular abnormalities included epiretinal membranes (51.1%), cystoid macular edema (18.4%), vitreomacular traction syndrome (2.4%), macular holes (2.3%) and choroidal neovascular membranes (0.05%). Glaucoma was found in 35 eyes (1.6%). The proportions of epiretinal membranes (p=0.001) and macular holes (p=0.008) increased significantly with age. Cystoid macular edema was significantly associated with poorer visual acuity in RP patients with clear lens (p=0.002).Conclusion Cataracts and macular abnormalities are common in RP patients. Of the macular abnormalities, cystoid macular edema may have a negative effect on BCVA in RP patients with clear lens. Therefore, optical coherence tomography screening in RP patients is highly recommended for early detection and treatment of maculopathy.

Cystoid macular oedema was significantly associated with poorer visual acuity in RP patients with clear lens (P = 0.002).Conclusion: Cataracts and macular abnormalities are common in RP patients. In the macular abnormalities, cystoid macular oedema may have a negative effect on BCVA in RP patients with clear lens.

Introduction. The aim of the study was to evaluate the effects of intravireal injections of aflibercept (Eylea) on bilateral cystoid macular edema in a patient with retinitis pigmentosa. Material and Methods. A 17-year-old man presented with a moderate bilateral decrease of visual acuity (0.3) and ocular examination was performed. Optical coherence tomography imaging was performed and cystoid macular edema was detected in both eyes. Due to disease progression in a short period of time, intravitreal repeated injections of aflibercept (Eylea) were initiated according to recent clinical reports. Results. The initial values of cystoid macular edema before intravitreal therapy were 248 ?m in the right and 237 ?m in the left eye; they increased slowly in next several weeks. Four bilateral repeated doses of intravitreal aflibercept injections at 6-week intervals were given in local anesthesia. The patient reported a subjective improvement, and his visual acuity was 4/10 in both eyes. Objectively, the macular edema decreased at week 24, reaching 173 ?m in the right and 188 ?m in the left eye. Conclusion. There are few literature reports on the possible effects of intravitreal aflibercept injections in the treatment of retinitis pigmentosa-related cystoid macular edema. In our study, bilateral macular edema in a patient with retinitis pigmentosa has improved significantly after four consecutive treatments. Further studies are necessary with a larger sample size and longer follow-up period to obtain information on the role and safety of intravitreal drugs for cystoid macular edema in retinitis pigmentosa. <br><br><font color="red"><b> This article has been corrected.

Purpose: The long-term clinical outcomes of cataract surgery in patients with retinitis pigmentosa (RP) were evaluated. Methods: A retrospective analysis of medical records was performed for patients who were diagnosed with RP and underwent cataract surgery. Preoperative best-corrected visual acuity (BCVA) was compared with BCVA at 1 month postoperatively and at the final visit. The proportion of patients with cystoid macular edema development or aggravation after surgery was evaluated, as was the proportion of patients with intraocular lens subluxation/dislocation. For patients who underwent optical coherence tomography, factors associated with a BCVA of 0.5 or better at 1 month were analyzed. Results: In total, 133 eyes were included and the mean follow-up period was 58.7 months. The mean logarithm of minimal angle of resolution BCVA was 0.69 ± 0.65 at diagnosis. The BCVA was significantly improved to 0.51 ± 0.47 at 1 month postoperatively (p < 0.001). However, the BCVA at the final visit (0.70 ± 0.81) was similar to the baseline value (p = 1.000). Cystoid macular edema development or aggravation was noted in 8 eyes (6.0%) and intraocular lens subluxation/dislocation was noted in 4 eyes (3.0%). A subgroup analysis involving 108 eyes revealed that preoperative BCVA (p < 0.001) and ellipsoid zone status (p = 0.001) were associated with postoperative visual acuity. Conclusions: Short-term outcomes of cataract surgery in patients with RP were comparatively good. However, long-term visual deterioration was noted with disease progression. Preoperative BCVA and ellipsoid zone status are useful markers for predicting short-term visual outcomes.

We present a case of retinitis pigmentosa (RP) related cystoid macular edema (CME) refractory to oral acetazolamide and topical ketorolac that was treated with intravitreal and subtenon depot triamcinolone. A 32-year-old male with RP presented with complaints of bilateral decrease in visual acuity. His best-corrected visual acuity (BCVA) was 20/50 in the right eye and 20/100 in the left eye. After being informed of the available treatment options, the patient received bilateral intravitreal injection triamcinolone. The patient’s BCVA improved to 20/40 in the right eye and 20/50 in the left eye and the CME was resorbed. However, 5 months after the injection in the left eye and two months in the right eye, visual acuity decreased due to recurrence of CME. We performed a second intravitreal injection in the left eye with improvement of visual and anatomic results, but we observed a recurrence of CME. Afterwards, we treated the patient with subtenon depot triamcinolone in both eyes, with the result that there was no recurrence after 4 months in OD or after 3 months in OS. We conclude that intravitreal and subtenon depot triamcinolone appear to provide at least temporary benefit in refractory CME as regards the improvement of visual acuity.

Abstract Background Retinitis pigmentosa (RP) is a heterogeneous group of inherited ocular diseases that result in progressive retinal degeneration. This study aims to describe different Swept-source Optical Coherence Tomographic (SS-OCT) changes in Palestinian RP patients and to explore possible correlations with Visual Acuity (VA). Methods A cross-sectional observational study was conducted on Retinitis Pigmentosa patients diagnosed with RP in a tertiary eye hospital. Full history and ocular examination were made. SS-OCT imaging was done for all eyes assessing the presence of cystoid macular edema, epiretinal membrane, macular holes, and external limiting membrane, ellipsoid zone status. Also, central macular thickness and choroidal vascular thickness were measured. Results The study was run on 161 eyes of 81 patients; 53 males and 28 females. The average age at examination was 26.1 (6–78) years. Twenty-six eyes (16.1%) were of syndromic RP patients, mostly Usher syndrome; 20 eyes (12.4%). The mean Logaritmic minimal angle of resolution (LogMAR) of Best Corrected Visual Acuity (BCVA)of the study sample was 0.66 ± 0.7. The most prevalent change was cystoid macular edema [28 eyes, (17.4%)], followed by epiretinal membrane [17eye, (10.6%)]. A macular hole was noted only in one eye (0.6%). Ellipsoid zone and external limiting membrane were absent in 55 eyes (35.0%) and 60 eyes 37.5%. Vitreous hyperreflective foci were found in 35 eyes (43.8%). LogMAR of BCVA was associated significantly with cystoid macular edema (p = 0.001), ellipsoid zone(p = 0.001), and external limiting membrane (p = 0.001). Conclusions Detailed SS-OCT assessment in Palestinian patients diagnosed with RP identified different morphologies from other populations. Cystoid macular edema and vitreous hyperreflective foci may reflect signs of early or intermediate stages of the disease. Disease progression can be monitored by measuring the length/width (area) of ellipsoid zone +/− external limiting membrane and choroidal vascular thickness, which should be evaluated serially using high-resolution OCT.
