“…Although it is too early to predict how many RBVA possibilities may exist, it is worth mentioning that a recent publication included fundus pictures (OD and OS) in which the ONH RBVA was similar to that of subjects II-11 and II-12 in our pedigree. 12 In this study, pattern O was seen in OD and pattern A in OS, a presentation identical to that of our subject II-12 ( Fig. 4B).…”

“…In addition, the unusual combination of pattern A and pattern O observed in twins ll-11 and ll-12 was also seen elsewhere. 12 To us, these findings suggest that these ONH RBVA patterns are not fortuitous observations; rather, they are real, genetically determined, and transmissible as a familial trait. Another limitation is the possibility that the specific patterns of the ONH RBVA could be altered or modified by a given disease process known to affect the retinal vasculature at the ONH, such as glaucoma, hypertension, cerebrospinal fluid pressure, or even hematocrit level.…”

It has been suggested that retinal blood vessel arborization (RBVA) is unique to each individual. We examined this claim in a pedigree that included two pairs of monozygotic twins. Methods: Fundus photographs were taken of subjects belonging to this pedigree to compare the pattern of their RBVA. Pattern prevalence within the general population was estimated from a pre-existing clinical database. Results: The optic nerve head (ONH) RBVA disclosed the following patterns: pattern A, outgrowth, with angle sizes ranging from 12°to 86°, toward the macula, made by the central retinal (CR) vein; pattern O, circular shape delimited by the CR artery on the nasal side and CR vein on the temporal (macula) side; and pattern Y, a double-Y shape (upright in the superior retina and upside down in the inferior retina) made by the four branches-inferior temporal and nasal and superior temporal and nasal-of the CR artery. The prevalence of patterns A, O, and Y was estimated at 11%, 2.8%, and 2.7%, respectively, from our pre-existing clinical database. Pattern A was the most frequently noted in our pedigree, with a prevalence of 26% to 29%, a value significantly larger (P < 0.05) than that measured in our sample of the general population. Of note, familial similarity is progressively lost as we move away from the ONH. Conclusions: Relatives appear to share similar ONH RBVA patterns, suggesting that the ONH RBVA could be genetically transmitted as a familial trait. Arrangement of the more peripheral retinal blood vessels would create individuality. Translational Relevance: Our results suggest the existence of a specific, reproducible, and transmissible retinal identifier, a feature that could potentially be associated with the prevalence of a given disease process, thus offering the possibility of identifying an underlying retinopathy long before its clinical manifestation and consequently optimize its management.

“…In Mexico, there are no organizations that regulate the manufacture of commercial lasers, which has produced an increase in the occurrence of cases 12 . Associations such as the American National Standard for Safe Use of Lasers classify them based on their safety as potentially harmful to the eye when the output power is > 5 mW, and capable of producing serious eye damage when the output power is more than 500 mW.…”

“…It is recommended for hemorrhages > 3 disc diameters, but its association with a macular hole has limited its use 2,20 . Vitrectomy with or without internal limiting membrane peeling has shown to induce a significant and immediate visual improvement and can prevent complications such as amblyopia or myopia in children, as well as those derived from the lack of an adequate evaluation of the deeper layers 2,12,20 . Other techniques such as hemolysis and pneumodisplacement have been described 15 ; however, they require the use of drugs that are difficult to handle and are mainly described for the treatment of subretinal hemorrhages.…”

This is the case of a 26-year-old man that presented a visual acuity decrease after unintentionally looking at a light projected in a laser show. On examination, a premacular hemorrhage was observed in the left eye. Optical coherence tomography demonstrated the presence of a sub-inner limiting membrane hemorrhage. A pars plana vitrectomy was performed with internal limiting membrane peeling, followed by rapid visual acuity improvement.

Purpose To describe two cases of macular hemorrhage in young patients, both occurred after laser exposure and cannabinoid intake during a disco party. Observations Case 1: a 21-year-old man was evaluated at our Emergency Unit for sudden vision loss in the right eye (RE). Best-corrected visual acuity (BCVA) was count fingers in the RE and 20/20 in the left eye (LE). Fundus examination revealed a broad pre-retinal hemorrhage in macular region of RE, confirmed by optical coherence tomography. The patient reported vision loss, suddenly occurred after fixation of a laser source and cannabinoid intake during a disco party the night before. We administered a macular supplement and closely followed up the patient. After two months BCVA of the right eye was 20/20. Case 2 The following day another 21-year-old man was referred to our Emergency Unit complaining of sudden vision loss in LE. As in Case 1, he reported to have fixed a laser beam as well as the consumption of cannabinoids at the same disco. BCVA was count fingers in the LE and 20/20 in the RE. Fundus examination showed a broad pre-retinal hemorrhage in macular region of LE. He had taken the macular supplement for two months and then the hemorrhage was reabsorbed. Conclusion and importance Laser exposure must be considered as a possible cause of macular hemorrhage. Furthermore, low cost of drugs and lack of formal control of laser sources may increase the emergence of new cases of retinal injuries especially among young people.
