Update on the diagnosis and treatment of choroidal hemangioma.

Choroidal hemangioma (CH) is a benign vascular tumor dependent on the choroid. Two types of lesions are distinguished: circumscribed (CCH), the most frequent variant, and diffuse (DCH), normally associated with Sturge-Weber syndrome. HCC appears as an orange mass that can present asymptomatically, however, when it produces symptoms, the most frequent is decreased visual acuity due to neurosensory retinal detachment. Due to its benign nature, only those that produce symptoms should be eligible for treatment. Knowledge of this pathology and its correct differential diagnosis is very relevant to establish the appropriate diagnosis and treatment, avoiding unnecessary treatments. There is currently a wide variety of multimodal diagnostic imaging tests that allow us to identify and adequately monitor this tumor. In addition, in recent years, there has been a change in the paradigm of the treatment of these tumors thanks to the use of photodinamic therapy, which has led to a significant improvement in the visual prognosis of these patients. This has been due to the use of photodynamic therapy as the treatment of choice for HCC.

Hypertensive and HLA-B27 negative uveitis: Disease course and complications.

PURPOSE: To perform a retrospective analysis on patients with HLA-B27 negative hypertensive acute anterior uveitis. Aqueous humor samples were obtained on which a polymerase chain reaction (PCR) test was performed. The patients were then classified into 3 groups depending on whether they were positive for cytomegalovirus (CMV) or herpesvirus (HSV-VZV) or negative for both. MATERIAL AND METHODS: Different variables were collected in successive visits (baseline, 3, 6, and 12 months). The variables were age, sex, visual acuity, intraocular pressure (IOP), cells in the anterior chamber, retro-keratic precipitates, hypotensive treatment, glaucoma or retina surgery, corneal transplantation, and central thickness of the retinal nerve fiber layer. RESULTS: The sample was 36 patients, with a mean age of 59.78 ± 15.26 years. The mean baseline IOP value was 40 ± 10.42 mmHg in the CMV group compared to 23.8 ± 10.4 mmHg in the HSV-VZV, and 22.65 ± 9.9 mmHg in the negative group. The baseline frequency of retro-keratic precipitates, hypotensive treatment, glaucoma surgery, and corneal transplantation was higher in CMV positives. At one year, the loss of retinal nerve fiber layer and glaucoma surgery was greater in the negative group. In the 3 groups, there was a direct and positive correlation between IOP and inflammation in the anterior chamber. Being 0.94 (P = .05) for the positive for CMV, 0.24 (P = .75) in that of HSV-VZV, and 0.98 (P = .17) in the negative group. CONCLUSIONS: HLA-B27 negative hypertensive acute anterior uveitis with CMV positive has a more aggressive initial presentation. However, after one year, the glaucomatous damage is less than in the negative group. In hypertensive acute anterior uveitis, when inflammation in anterior chamber is controlled then IOP is also controlled.

However, after one year, the glaucomatous damage is less than in the negative group.

Combined cataract surgery and lamellar endothelial keratoplasty in iridocorneal endothelial syndrome. / Cirugía combinada de catarata y queratoplastia lamelar endotelial en el síndrome iridocórneo endotelial.

The case is reported of a 59-year-old woman, who reported decreased visual acuity (VA) in the left eye (LE). On examination, a corrected VA of finger count/ 30cm was observed in LE. Corneal oedema and folds in the Descemet's membrane were observed using the slit lamp. Anterior synechiae, iris atrophy, and corectopia were also found. Iridocorneal endothelial syndrome (ICE) was diagnosed. The treatment option was a combination of cataract surgery and automated endothelial keratoplasty with Descemet's membrane dissection (DSAEK). There were no complications during the operation, with a successful anatomical and functional recovery, with a VA of 0,8 being observed after one year. This result supports the efficacy of DSAEK in ICE syndrome, encouraging more studies to be carried out that should also support its efficacy in this syndrome.

The correlation between the thickness of the inner macular layers and the mean deviation of the visual field in children with primary congenital glaucoma. / Correlación entre el grosor de las capas internas de la retina y el defecto medio del campo visual en pacientes con glaucoma congénito primario.

PURPOSE: To analyse the association between the thickness of the circumpapillary retinal nerve fibre layer (cpRNFL) and the thickness of the inner macular layers with the mean deviation of the visual field (MD) in children with primary congenital glaucoma (PCG). MATERIAL AND METHODS: A total of 41 children with PGC were included in the study. They all had a complete ophthalmological examination, including visual acuity, intraocular pressure, funduscopy, Octopus™ visual field, as well as circumpapillar and macular spectral domain optical coherence tomography (SD-OCT). SD-OCT with automated segmentation was used to measure the thicknesses and volumes of the macular retinal nerve fibre layer (mRNFL), ganglion cell layer (GCL), and inner plexiform layer. RESULTS: The mean age was 11.2±3.86 years, and the mean MD was 8.85±6.76dB. The visual field was classified as normal in 46% of the patients, and 20% of the patients had a concentrical restriction of the visual field. A positive correlation was found between between the cup-to-disc ratio and the MD, r=0.51 (P=.004). The correlation between the MD and the cpRNFL was r=-0.63 (P<.001), and r=-0.69 (P<.001) with the GCL. CONCLUSIONS: Inner macular layers thickness and cpRNFL thickness show a good correlation with the mean deviation of the visual field in children with primary congenital glaucoma.
