Estimated intracranial pressure in glaucoma patients and its correlation with disease severity.

PURPOSE: To compare the intracranial pressure (ICP) and the translaminar pressure difference (TLPD) between primary open-angle glaucoma (POAG) patients and non-glaucoma subjects and to assess the correlation between the ICP (and TLPD) and glaucoma severity. METHODS: This was a cross-sectional study. Patients with POAG and age-matched controls were included. ICP was calculated using proxy algorithm to attain indirect surrogate parameter values. Differences were compared between groups. The correlation between ICP (and TLPD) and both structural and functional variables was evaluated using linear and non-linear regression analysis and estimated with Pearson's correlation coefficient. RESULTS: Fifty patients with POAG and 25 normal controls were included. The mean estimated ICP was lower in POAG (10.9 ± 3.2 mmHg) as compared to controls (15.0 ± 3.7 mmHg, p < 0.001). The TLPD was higher in POAG (2.6 ± 4.1 mmHg) when compared to non-glaucoma (-0.3 ± 3.6 mmHg, p = 0.002). ICP displayed a negative correlation with cup-to-disk ratio (r = -0.566; 95% CI, -0.699 to -0.369, p'0.000) and a positive correlation with retinal nerve fiber layer thickness (r = 0.441; 95% CI, 0.230 to 0.612; p'0.000). There was a positive correlation between ICP and mean deviation (r = 0.280; 95% CI, 0.05 to 0.482, p = 0.017). CONCLUSION: Glaucoma patients presented lower ICP values; lower ICP values were associated with more advanced disease. These observations strengthen the role of ICP as a potential player on the glaucoma pathogeny.

Conjunctival tattoo: report on an emerging body modification trend.

We report the case of a patient who received conjunctival tattooing for cosmetic purposes with associated complications. A 28-year-old male experienced severe ocular pain after undergoing conjunctival tattooing. Slit-lamp examination revealed blue deposits over the conjunctiva in association with intense conjunctival edema and a 4+ anterior chamber cellular reaction. The patient underwent clinical treatments to control ocular inflammation. Two months after the injury, the patient was still in follow-up to ensure that any further complications were managed and documented. This unusual case of conjunctival tattooing resulted in conjunctival edema and anterior uveitis. Because of the increasing popularity of eyeball tattooing, the potentially severe complications of this procedure may become more common.

ABSTRACT We report the case of a patient who received conjunctival tattooing for cosmetic purposes with associated complications.

RESUMO Relatamos um caso de um paciente que realizou tatuagem conjuntival para fins cosméticos com complicações associadas. Um homem de 28 anos de idade apresentou dor ocular importante após tatuagem conjuntival. O exame da lâmpada de fenda revelou depósitos azuis sobre a conjuntiva, associados a um intenso edema conjuntival e uma reação de câmara anterior de 4+ de células. O paciente foi submetido a tratamentos clínicos para controlar a inflamação ocular. Dois meses após o ocorrido, o paciente ainda estava em acompanhamento para garantir que quaisquer outras complicações fossem gerenciadas e documentadas. Um caso incomum de tatuagem conjuntival resultou em edema conjuntival e uveíte anterior. Devido à crescente popularidade da tatuagem no globo ocular, complicações potencialmente graves deste procedimento podem se tornar mais comuns.

Conjunctival Tattoo With Inadvertent Globe Penetration and Associated Complications.

PURPOSE: To report a case of conjunctival tattooing for cosmetic purposes with inadvertent globe penetration resulting in severe inflammation, capsular lens opacity, and secondary glaucoma. METHODS: Case report. RESULTS: A 25-year-old woman experienced severe ocular pain and decreased vision in the left eye after conjunctival tattooing for cosmetic purposes on the previous day. Slit-lamp examination revealed black deposits over the conjunctiva, corneal endothelium, anterior chamber angle, iris, and anterior capsular lens due to the tattooing pigment. In addition, severe anterior uveitis triggered by the pigments and, later, secondary glaucoma were diagnosed. The patient underwent clinical and surgical treatments to control ocular inflammation and intraocular pressure. Three months after the injury, the patient was still under follow-up treatment in an effort to control the complications of the eyeball tattooing. CONCLUSIONS: An unusual case of conjunctival tattooing resulted in severe inflammation, capsular lens opacity, and secondary glaucoma. Because of the increasing popularity of eyeball tattooing, coupled with the procedure being performed by untrained professionals, potentially severe complications of this procedure may become more common.
