Key result
Transient dark-without-pressure fundus lesions are linked predominantly to sickle cell hemoglobinopathies.
Case Report (n=7)
Answers are grounded in this paper and cite their sources.
Seven black patients had dark brown homogeneous geographical areas of the fundus. Six cases were associated with sickle cell haemoglobinopathies and one was associated with systemic hypertension. These flat lesions were uniform in colour and occurred in the posterior pole or in the midperiphery. They appeared to be transient and often disappeared leaving no residue. The cause is unknown. By analogy with white-without-pressure fundus lesions, we have called these areas dark-without-pressure.

Nagpal et al. (1975) conducted a case report in Dark-without-pressure fundus lesions (n=7). Sickle cell haemoglobinopathies and systemic hypertension was evaluated on Clinical characteristics and disease associations.
