A method of treating ocular hypertension which comprises applying to the eye an amount sufficient to treat ocular hypertension of a compound of formula (I) ##STR4## wherein either the cyclopentane(ene) radical or the .alpha. or .omega. chain may be unsaturated;
- R is pyridyl;
- R.sub.1, R.sub.2 and R.sub.3 are selected from the group consisting of hydroxy and hydrocarbyloxy radicals wherein said hydrocarbyloxy radical comprises up to 20 carbon atoms;
- Y an oxo radical and X represents an amino or a mono or dialkyl amino radical;
- provided, however, at least one of R.sub.1, R.sub.2 and R.sub.3 is a hydrocarbyloxy radical.
