We systematically reviewed the literature on previous intravitreal injections as a risk factor of PCR and performed meta-analyses to provide pooled summary risk estimates.Methods: We searched 13 literature databases on 1 June 2021 for studies evaluating the risk of PCR in eyes undergoing cataract surgery with data on previous intravitreal injections. Data extraction was made independently by two authors and discussed afterwards until reaching consensus. Random effects metaanalyses on the pooled odds ratio (OR) of PCR in eyes with previous intravitreal injections were made using MetaXL 5.3.Results: Six studies on 1 051 097 eyes undergoing cataract surgery were eligible for the qualitative and quantitative review. Previous history of intravitreal injections was present in 7034 eyes (majority was anti-VEGF). Our metaanalyses revealed that any previous intravitreal injection was a risk factor for PCR with an OR of 2.30 (95% CI 1.39-3.81). For each previous intravitreal injection, the risk of PCR was OR 1.04 (95% CI 1.01-1.08) (equivalent of relative risk similar to 1.04). In other words, risk of PCR increases by 4% for each previous intravitreal injection.Conclusions: Previous intravitreal injection is a risk factor for PCR and should be taken into account when planning cataract surgery. However, to be regarded as a clinically significant risk of PCR, a substantial number of previous intravitreal injection (e.g. >= 10) should have been administered, considering that the a priori risk of PCR is very low (similar to 1%).

Show moreThis study investigated the phenotypic spectrum of PHARC (polyneuropathy, hearing loss, ataxia, retinitis pigmentosa and early-onset cataract) syndrome caused by biallelic variants in the ABHD12 gene. A total of 15 patients from 12 different families were included, with a mean age of 36.7 years (standard deviation [SD] +/- 11.0; range from 17.5 to 53.9) at the most recent examination. The presence and onset of neurological, audiological and ophthalmic symptoms were variable, with no evident order of symptom appearance. The mean best-corrected visual acuity was 1.1 logMAR (SD +/- 0.9; range from 0.1 to 2.8; equivalent to 20/250 Snellen) and showed a trend of progressive decline. Different types of cataract were observed in 13 out of 15 patients (87%), which also included congenital forms of cataract. Fundus examination revealed macular involvement in all patients, ranging from alterations of the retinal pigment epithelium to macular atrophy. Intraretinal spicular hyperpigmentation was observed in 7 out of 15 patients (47%). From an ophthalmic perspective, clinical manifestations in patients with PHARC demonstrate variability with regard to their onset and severity. Given the variable nature of PHARC, an early multidisciplinary assessment is recommended to assess disease severity. Show less
