ABSTRACT

Hermansky-Pudlak syndrome (HPS) is a rare autosomal recessive disorder characterized by oculocutaneous albinism, bleeding diathesis, and ceroid deposition leading to complications such as pulmonary fibrosis and colitis. This case report describes a 63-year-old female with HPS type 1 (HPS1) who developed acute angle closure glaucoma following cataract surgery with anterior intraocular lens implantation. The patient presented with severe acute pain in the right eye, which was diagnosed as a pupillary block leading to acute angle closure glaucoma. Preoperative planning included the administration of aminocaproic acid to mitigate bleeding risk, given the patient's underlying bleeding diathesis. Yttrium aluminium garnet (YAG) laser iridotomy was performed, resulting in a significant reduction of intraocular pressure and stabilization of the patient's condition.

ABSTRACT

This case report details the clinical manifestations observed in a 22-year-old male diagnosed with ocular albinism (OA). The patient underwent a comprehensive eye examination by one of the authors, revealing clinical features such as skin depigmentation, telecanthus, iris transillumination, nystagmus, and foveal hypoplasia. This report underscores the importance of a thorough clinical examination and genetic testing for accurate diagnosis, effective management, and appropriate counseling of patients with OA.

ABSTRACT

Mutations in the KIF7 gene have been implicated in autosomal recessive conditions such as Joubert syndrome, acrocallosal syndrome, and fetal hydrolethalus, as well as in retinal degeneration and other ocular manifestations due to their effect on primary cilia. In this study, we report that the full-field electroretinogram (ERG) test showed non-recordable scotopic ERG responses, while photopic ERG responses were diminished bilaterally. This is a case report of a 62-year-old female patient with painless, progressive vision loss in both eyes. Fundus examination revealed a pale optic nerve head, vessel attenuation, and macular thinning without peripheral pigmentary changes. The full-field electroretinogram (ERG) test showed non-recordable scotopic ERG responses, while photopic ERG responses were diminished bilaterally. Based on these ocular findings, the patient was clinically diagnosed with retinitis pigmentosa (RP) sine pigmento. Genetic testing identified a pathogenic heterozygous mutation in the KIF7 gene with the variant c.61C>T (p.Arg21*). Our case suggests that this pathologic variant may be associated with RP sine pigmento. Further studies are warranted to better understand the role of the KIF7 gene in retinal dystrophies.

ABSTRACT

Oculopharyngeal muscular dystrophy (OPMD) is a late-onset inherited skeletal myopathy. The diagnosis is based on a clinical presentation of blepharoptosis, dysphagia, and a positive family history of the disease in patients past 40 years of age. A 57-year-old male patient presented with ptosis without lid crease, adult-onset dysphagia, and bilateral pseudophakia. The patient underwent ptosis repair of upper eyelids via frontalis slings with silicone rods. His mother was subsequently found to have ptosis, dry eyes, and anorexia due to dysphagia, thus suggesting a probable family history. Based on the comprehensive ophthalmic evaluation, and based on his ptosis, dysphagia, and family history, the patient was diagnosed with OPMD.

ABSTRACT

Patients with Marfan syndrome have a constellation of clinical features and a heterogeneous phenotype. The purpose of this study is to report a 47-year-old male patient with an unusual variant in the FBN1 gene causing Marfan syndrome. The patient with musculoskeletal, cardiovascular, and ocular findings compatible with Marfan syndrome had an unusual pathogenic mutation on the FBN1 gene. The patient was examined by at least one of the authors (NJI). The patient's clinical findings were compatible with Marfan syndrome. Our patient had a unique mutation in the FBN1 gene (c.8054A>G p.His2685Arg) located on exon 65. Next-generation sequencing was done using the Invitae panel. This variant was categorized as one of uncertain significance. This patient's variant on the FBN1 gene leading to the syndrome has scant data associated with it and this is the first time it is reported from Puerto Rico.

ABSTRACT

Our purpose is to report a patient with a novel variant in the fibrillin-1 (FBN1) gene causing the Marfan syndrome (MFS). The 29-year-old female patient with musculoskeletal, cardiovascular, and ocular findings compatible with the MFS had a novel pathogenic mutation on the FBN1 gene. We report on a patient whose clinical findings are compatible with the MFS. This patient's variant on the FBN1 gene leading to the syndrome has not been previously described. Additional investigations are needed to determine whether this variant contributes to the development of camptodactyly in patients with the syndrome.

ABSTRACT

Previous studies have reported that patients with retinitis pigmentosa (RP) may develop open-angle and angle-closure glaucoma. We conducted a chart review of patients with RP. Two siblings with RP associated with a mutation in the PDE6B gene (c. 1540del, p.Leu514Trpfs*61) developed cystoid macular edema (CME) as part of the disease. For this reason, they both underwent intravitreal steroid injections. Both brothers developed steroid-induced glaucoma (SIG). Despite undergoing maximal medical therapy, they underwent seton implants to control their intraocular pressure. A third female patient with RP due to a mutation in the RPGR gene underwent cataract surgery. Topical steroids were prescribed and developed SIG. Increased intraocular pressure remains a complication of topical, injected, and systemic steroids. However, steroids may be needed to treat post-operatively and patients with CME. This case series unveils a complex association between RP and key comorbidities in these patients, with a focus on cataracts, glaucoma, and macular edema. Cataract surgery in patients with RP shows a link to the emergence of glaucoma, particularly in those with RPGR and PDE6B gene mutations, revealing a novel association with PDE6B mutations not previously documented. Furthermore, the paper explores a unique parallel with Schwartz-Matsuo syndrome, suggesting that patients with RP undergoing cataract surgery may develop increased intraocular pressure due to an outflow disturbance akin to Schwartz syndrome. This novel perspective deepens our understanding of the pathophysiological mechanisms governing intraocular pressure dynamics in patients with RP. To our knowledge, this is the first report of steroid-induced glaucoma in patients with RP due to mutations in the PDE6B gene. Intraocular pressure evaluation remains of utmost importance in the follow-up of patients with the disease.

ABSTRACT

Patients with mutations in the α/ß-hydrolase (ABHD) 12 gene develop ocular complications including cataracts and retinitis pigmentosa (RP), as part of the polyneuropathy, hearing loss, ataxia, RP, and cataract (PHARC) syndrome. A chart review on a patient with a heterozygous mutation on the ABHD12 gene underwent a comprehensive ophthalmic evaluation. Visual acuity was 0 and 1.3 (logMAR) on the right eye (OD) and left eye (OS), respectively. There was pseudophakia in the OS. Fundus examination in OD was normal and pale optic nerve, attenuated vessels, cystoid macular edema, and mid-peripheral bony spicules were found in OS. Visual field test showed a ring scotoma in the OS. Macular optical coherence tomography (OCT) and fundus autofluorescence were compatible with cystoid macular edema of the OS. The electroretinogram (ERG) of left eye was flat. Patient's systemic findings included: polyneuropathy and hearing loss. Unilateral presentation of cataract and RP in a patient with a heterozygous pathogenic mutation on the ABHD12 gene is rare. This could be due to mosaicism. Retinal follow-up is warranted in this patient since manifestations may occur later in the contralateral eye. A heterozygous pathogenic mutation on the ABHD12 gene may lead to partial ocular and systemic manifestations of the PHARC syndrome.

ABSTRACT

We report on a case of a 34-year-old Hispanic female patient with a medical history of diabetes mellitus, thyroid disease, and cataract surgery in the right eye, who was evaluated due to progressive vision loss in both eyes. The patient had waxy pallor of the optic disc, vessel attenuation, retinal pigment epithelium (RPE) degeneration, and bony spicules OU. These findings are compatible with a diagnosis of retinitis pigmentosa (RP). Gene sequencing and deletion/duplication analysis were performed. The patient was positive for a heterozygous mutation in the PRPF6 gene with the variant c.2228C>T (p.Thr743Ile). This PRPF6 variant was reported as a variant of unknown significance. The Combined Annotation Dependent Depletion (CADD) score of this PRPF6 variant is 23.5, which strengthens the idea that it could potentially be associated with RP. To our knowledge, this is the first case reported on an RP patient with the PRPF6 variant c.2228C>T (p.Thr743Ile). Our case suggests that this PRPF6 variant may be associated with bilateral RP. Further molecular studies are warranted to better understand the molecular changes in the PRPF6 gene leading to RP.

ABSTRACT

Patients with adult Refsum Disease (ARD) have retinitis pigmentosa and thus nyctalopia, anosmia, sensorineural deafness, polyneuropathy, and ataxia. Upon physical examination, patients with ARD have congenital short metacarpals, metatarsals, and cardiac arrhythmias. Manifestations due to the lack of phytanoyl-CoA hydroxylase in peroxisomes needed for alpha-oxidation of phytanic acid lead patients to accumulate phytanic acid in their body tissues. To our knowledge, no consensus for clinical diagnostic criteria for patients with ARD has been published. Our patient had nyctalopia, retinal findings, and visual field results compatible with retinitis pigmentosa. Additionally, the patient had decreased macular thickness and volume in both eyes, the findings being worse in the left eye. The patient had undergone hand surgery due to chronic pain in both hands, as well as his fourth and fifth metatarsal bones were shortened. Interestingly, audiology evaluation showed mild hearing loss in the right ear and mild to moderate hearing loss in the left ear. Inheritance patterns in patients with ARD have been described. Physical examination, phytanic acid evaluation, and genetic studies may all help reach an ARD diagnosis. This is the first report of adult Refsum disease in Puerto Rico.

ABSTRACT

We report two patients with musculoskeletal manifestations as part of the Bardet-Biedl syndrome. The first patient (case 1) was born with polydactyly and later diagnosed with coxa vara. He had homozygous pathogenic mutation in the BBS1 gene of the variant c.1645G>T (p.Glu459*). The second patient (case 2) had nyctalopia and progressive vision worsening had osteoarthritis symptoms. He had a heterozygous mutation in the BBS1 gene of the variant c.1169T>G (p.Met390Arg). Although polydactyly is the most prevalent musculoskeletal association in patients with the syndrome, co-management of the musculoskeletal manifestations remains of utmost importance in patients with the syndrome.

ABSTRACT

We report a carrier of Usher syndrome type I with retinitis pigmentosa sine pigmento. A 71-year-old male was referred for further evaluation of severe, progressive, painless vision loss in both eyes over the course of four years. He had bilateral sensorineural hearing loss. Upon a comprehensive examination, his best-corrected visual acuity was 20/100 in the right eye and 20/40 in the left eye. He had an unremarkable anterior segment examination and normal intraocular pressures in both eyes. Upon fundus examination, the patient had pale discs, optic disc cupping, and multiple scattered drusen in the macula and at the midperiphery of both eyes. Optical coherence tomography showed retinal nerve fiber layer thinning in all quadrants. The visual field was severely constricted in both eyes. A comprehensive workup for infectious and inflammatory causes, as well as a brain MRI, was unremarkable. Sequencing analysis showed that he carried a heterozygous pathogenic mutation, USH1C c.672C>A (p.Cys224*) variant. Usher syndrome is a rare genetic disease characterized by hearing loss and retinitis pigmentosa. Our case suggests that patients and carriers of Usher syndrome may have a phenotype compatible with retinitis pigmentosa sine pigmento.

ABSTRACT

Mutations in the phosphodiesterase 6B (PDE6B) gene are a rare cause of autosomal recessive retinitis pigmentosa (arRP). We report on a non-consanguineous family with a pseudodominant inheritance of RP due to PDE6B mutations. We conducted a chart review of four members of a Puerto Rican family who underwent a comprehensive ophthalmic evaluation by at least one of the authors. The mutational screening was done using a genotyping microarray provided by Invitae Corporation, using next-generation sequencing (NGS) technology. Genomic DNA obtained from saliva samples is enriched for targeted regions using a hybridization-based protocol and sequenced using Illumina technology. A descriptive analysis was done. Patient 1A had a normal ophthalmic examination and a heterozygous pathogenic variant in the PDE6B gene c.1540del PLeu514Trpfs*61. Patients 1B, 2A, and 2B had mid-peripheral retinitis pigmentosa, concentric visual field ring scotomata in both eyes (OU), extinguished electroretinogram (ERG), and homozygous pathogenic variants in the PDE6B gene c.1540del PLeu514Trpfs*61. Even though mutations in the PDE6B gene usually lead to arRP, they may be inherited in a pseudodominant pattern in geographically isolated populations. Genotyping studies in patients with RP are warranted to classify inheritance mode correctly.

ABSTRACT

INTRODUCTION: It is possible that social media use can boost not just articles' social impact but the number of citations and academic influence as well. If a positive correlation between Twitter usage and citation metrics exists in the ophthalmology literature, it is important to broadcast this information to the ophthalmology community so they can use Twitter to increase academic engagement with their research. There has also been an increase in the number of articles available as open access. Therefore, it is important to evaluate the presence of an open-access citation advantage in the field of ophthalmology. This study aims to evaluate the relationship between Twitter mention and open access status on citation metrics in the ophthalmology literature. METHODS: We conducted a retrospective cross-sectional study comparing article citation metrics to Twitter mentions and open access status. We gathered data on ophthalmology research articles from the six highest-ranked ophthalmology journals published as part of a January 2019 issue. Data were collected in April 2022, 38 months after online publication. Data on citations for each article was based on Google Scholar and Scopus websites. The Altmetric Bookmarklet extension was used to determine the amount of social engagement each article received. The open-access status of each article was based on the status listed in its corresponding journal. Two-tailed t-tests were used to compare social media engagement and open access status with the number of Google Scholar and Scopus citations. RESULTS: A total of 102 original research articles were analyzed. 89 (87.3%) articles received a Twitter mention. Articles tweeted at least once had a significantly higher Google Scholar score (27.2 +/- 4) compared to articles not tweeted (16.4 +/- 1.7; 1.7-fold increase, p<0.05). Likewise, the average Scopus score was significantly higher for tweeted articles (18.6 +/- 2.6) compared to articles not tweeted (11.8 +/- 1.6; 1.6-fold increase, p<0.05). Articles listed as open access had a significantly higher number of Twitter mentions (11.8 +/- 1.8) compared to articles that were not open access (5.6 +/- 0.7; 2.1-fold increase, p<0.05). Open-access articles also had higher citation scores compared to articles that are not open access, but this relationship was not statistically significant. CONCLUSION: This is the first study to evaluate the relationship between article Twitter mention and citation score in the field of ophthalmology. It demonstrates a significant positive correlation between the article Twitter mention and citation score and provides further evidence that social media engagement can be beneficial to the dissemination of academic information. Further studies on the relationship between social media engagement and article dissemination are warranted in the field of ophthalmology.

ABSTRACT

Signal peptide (SP) mutations are an infrequent cause of inherited retinal diseases (IRDs). We report the genes currently associated with an IRD that possess an SP sequence and assess the prevalence of these variants in a multi-institutional retrospective review of clinical genetic testing records. The online databases, RetNet and UniProt, were used to determine which IRD genes possess a SP. A multicenter retrospective review was performed to retrieve cases of patients with a confirmed diagnosis of an IRD and a concurrent SP variant. In silico evaluations were performed with MutPred, MutationTaster, and the signal peptide prediction tool, SignalP 6.0. SignalP 6.0 was further used to determine the locations of the three SP regions in each gene: the N-terminal region, hydrophobic core, and C-terminal region. Fifty-six (56) genes currently associated with an IRD possess a SP sequence. Based on the records review, a total of 505 variants were present in the 56 SP-possessing genes. Six (1.18%) of these variants were within the SP sequence and likely associated with the patients' disease based on in silico predictions and clinical correlation. These six SP variants were in the CRB1 (early-onset retinal dystrophy), NDP (familial exudative vitreoretinopathy) (FEVR), FZD4 (FEVR), EYS (retinitis pigmentosa), and RS1 (X-linked juvenile retinoschisis) genes. It is important to be aware of SP mutations as an exceedingly rare cause of IRDs. Future studies will help refine our understanding of their role in each disease process and assess therapeutic approaches.

ABSTRACT

Background: Previous studies have reported on retinitis pigmentosa (RP) in Puerto Rico. Information on the geographic distribution of RP mutations in Puerto Rico may lead to higher rates of diagnosis and co-management. We aimed to evaluate whether there are areas with increased incidence of genes leading to RP in the Island. Materials and Methods: We conducted a non-concurrent prospective study on the genotype of 241 patients with RP in Puerto Rico. We evaluated their townships to determine whether there are clusters of genes leading to RP. Genetic studies were done using the Invitae inherited retinal diseases panel analyzing 330 genes. Results: A total of 100 patients were evaluated. Clusters of patients with mutations were found in certain townships. As depicted in the map, a cluster of patients with a mutation in the PDE6B gene was found in San Juan (9), those with the BBS1 gene occurred in San Juan (6) and Bayamón (4), mutations on the USH2A gene were found in Toa Baja (5), mutations in the CRB1 gene appeared in Ciales (4), and mutations in the BBS7 were found in Aibonito (2). Other mutations are scattered throughout the Island. Conclusion: Clusters of mutations were identified in several townships including San Juan, Bayamón, Toa Baja, Ciales, and Aibonito. Some of these are isolated geographically. Additional mutations were identified but only the most pertinent were reported. Genetic studies are warranted in all patients with RP in Puerto Rico.

ABSTRACT

INTRODUCTION: Cataract is the leading cause of blindness worldwide. Phacoemulsification is now the gold standard for cataract extraction and is greatly needed in low socioeconomic status (SES) communities, rural and older patient populations, and patients with poor vision. This greatly increases the importance of high readability for online resources on this topic. This study aims to assess the readability of online information about phacoemulsification based on readability scores for each resource.  Methods: We conducted a retrospective cross-sectional study. The term "phacoemulsification" was searched online, and each website was categorized by type: academic, physician, non-physician, commercial, social media, and unspecified. The readability scores for each website were calculated using six different readability tests and a composite score that reflects reading grade level was obtained. To evaluate the difference between the categories of websites, analysis of variance (ANOVA) testing was used. All test scores were compared with the 6th grade standard recommendation using a one-sample t-test. RESULTS: A total of 20 websites were analyzed. Three websites (3/20; 15%) had a score which is correlated with a 6th grade reading level or below. Seventeen websites had a score correlated with a college reading level or above (17/20; 85%). None of the readability scores had a mean below a 6th grade reading level. No category had an average readability score at or below a 6th grade reading level. None of the mean readability scores resulted in a statistically significant difference across categories. All readability tests had an average score which was significantly different from a 6th grade reading level (p<0.001).  Conclusions: This is the first study to focus on the accessibility of online English resources on phacoemulsification and implement multiple standardized readability scores with regards to cataract surgery resources. It provides further overwhelming evidence that online resources on phacoemulsification are too complex for the average patient to understand. Interventions should be implemented to improve readability.

ABSTRACT

OBJECTIVE: To determine the incidence of retinoblastoma (Rb) and the survival rate of patients with Rb in Puerto Rico. METHODS: This was a retrospective review of data from the Puerto Rico Central Cancer Registry (1985 - 2012). RESULTS: There were a total of 57 patients with Rb, with an overall incidence of 3.6 per 100,000 live births. By birth cohort, the incidence was 1 of every 29,393 live births. The mortality rate was 14.04% at 5 years. The incidence and the survival rate did not change over the 2 time periods that were compared: 1985 through 1998 and 1999 through 2012. CONCLUSION: The incidences of Rb are similar in Puerto Rico and the continental United States. However, our data indicate that the survival rate is lower in the former than it is in the latter. The incidence and the survival rate remained stable over the time studied.

ABSTRACT

Introduction Patients with Usher syndrome (USH) have retinitis pigmentosa (RP) and hearing loss inherited as an autosomal recessive (ar) trait. Mutations in the USH2A gene are the most common cause of Usher syndrome. We report the genotype-phenotype correlation in 10 patients with Usher syndrome from Puerto Rico (PR). This is the first genotype-phenotype analysis of patients with the syndrome in PR. Methods We conducted a chart review of patients who carried an Usher syndrome diagnosis. They underwent a comprehensive ophthalmic evaluation by at least one of the authors. This included best corrected visual acuity (BCVA), visual field mean deviation (VF MD), pattern standard deviation (PSD), and macular optical coherence tomography (mOCT) average volume and thickness. Genotyping was done using the Invitae Inherited Retinal Disease (IRD) Panel. Results Three patients had a logMAR BCVA of 1.0 or worse. The median VF MD was -29.7 dB and -29.2 dB in the OD and OS, respectively. The median PSD was 5.5 dB and 5.7 dB in the OD and OS, respectively. Upon macular OCT, patients had a median volume of 8.4 µm3 and 8 µm3 in the OD and OS, respectively. The median thickness was 235 µm and 223 µm in the OD and OS, respectively. All patients had pathogenic USH2A variants, and eight of these were compound heterozygotes. The most common variants were p.Cys575Tyr and p.Glu767Serfs*21, each present in four patients. Patients with the p.Cys759Phe variant had the worst phenotype with the worst BCVA, largest VF MD, and slimmer macular thickness. Conclusion Our findings are compatible with previously reported pathogenic mutations in the USH2A gene. However, the p.Cys759Phe variant has previously been correlated with a mild phenotype. In our study, the p.Cys759Phe variant correlated with the most severe phenotype. This variant has a high prevalence in the Spanish population, and PR was a Spanish colony for 400 years. The presence of this variant could be traced back to Spain. Genotyping patients with Usher syndrome is of utmost importance. Further studies to evaluate the common founder effect of patients with the syndrome in PR are warranted.

ABSTRACT

BACKGROUND: The Hermansky-Pudlak syndrome (HPS) is a genetically heterogeneous group of diseases characterized by oculocutaneous albinism, bleeding diathesis, and systemic complications. It is the most common genetic disorder in Puerto Rico. These patients are at a significant risk of developing a variety of skin complications and little is known about the prevalence of dermatologic diagnoses in this population. OBJECTIVES: To report dermatologic manifestations in patients with Hermansky-Pudlak syndrome (HPS). Secondary aims include skin concerns, sun protection habits, barriers to dermatologic care, and skin cancer knowledge. METHODS: Cross-sectional study with twenty-nine Puerto Rican patients who carried a clinical diagnosis of HPS type 1 or type 3 through a telephonic questionnaire. RESULTS: Twenty-nine patients participated with a mean (SD) age of 37.3 (16.8) years and the majority were female (69%). The most common diagnoses were skin cancer (34.5%), acne (34.5%), bacterial skin infections (34.5%), warts (24%), urticaria (17.2%), and psoriasis (17.2%). The most common skin concerns were dry skin (62.1%), hair loss (58.9%), redness (34.5%), moles (31%), and rash (31%). The most common sun protection behavior was wearing a shirt that covers the shoulders (93.1%, often or always) and the least common was wearing a hat (24.1%, often or always). Higher income was significantly associated with being more likely to use sunscreen often or always (OR = 3.38, 95% CI 1.02-11.18, p = 0.04). Those in northern urban areas were significantly less likely to report barriers to dermatologic care (OR = 0.13, 95% CI 0.02-0.76, p = 0.02). CONCLUSIONS: This study provides an important overview of the most common self-reported skin manifestations in patients with HPS. Unfortunately, a high prevalence of cutaneous malignancy was reported. The results stress the need for adequate care and potential interventions to promote sun protection behaviors and skin cancer prevention.
